Alanine is a naturally forming chemical found in a variety of foods especially meats. This non essential amino acid is used in the production of protein. It assists the body in metabolizing various components such as glucose and can also play a part in lowering cholesterol. It is suggested that an Alanine supplement be used with people who have a diet low in protein and who may be exposed to adverse effects of a protein deficiency. Alanine is also linked to an increase in the efficacy of the immune system and a reduction of toxins in the system.

Arginine is a non-essential amino acid that is needed by the body for the proper functioning of the liver, skin, joints, and muscles. It helps improve the immune system by increasing the T-lyphocytes output from the thymus gland. Arginine also neutralizes the effects of ammonia and toxic substances by detoxifying the liver. It is beneficial to most athletes particularly body builders because arginine helps in the production of creatine in the body and stimulates the excretion of growth hormones that aids in the development of muscle mass. It also helps improve the metabolism and in fat loss. Arginine also promotes the healing and repair of damaged tissues.

Aspartic Acid is a non-essential amino acid which is bountiful in plant proteins. It can also be produced in the human body from oxaloacetic acid. Some biochemicals that are synthesized from aspartic acid include asparagine, arginine, lysine, methionine, threonine, isoleucine, and a number of nucleotides. Apartic acid is used for stamina, the brain and overall health as it helps the liver by removing excess harmful ammonia and other toxins from the bloodstream. If ammonia enters your circulatory system it can be harm your central nervous system and cause neural and brain disorders. Aspartic acid helps to keep the mind sharp by increasing concentrations of NADH in the brain.

Cystine is a non-essential sulfur containing amino acid. Our body can supply cystine on its own. Cystine is important for vitamin B6 utilization and is a detoxifying agent. It removes toxins absorbed by body through alcohol and smoking and protects body from damage of brain and liver. Cystine increases the level of glutathione, which is a powerful antioxidant and helps in detoxifying harmful toxins in the liver. As Alpha-keratin, the protein that makes up the skin, fingernails and hair contains cystine; it is also used in anti-aging products. It is also useful for faster healing of burns and wounds, for low count of white blood cells and in skin diseases.

Glutamic Acid is an excitatory neurotransmitter, which enhances firing of neurons in central nervous system. Glutamic acid is a main excitatory neurotransmitter in brain and spinal caord. It is transformed either into glutamine or gamma-aminobutyric acid – the two other amino acids which assist in transmitting messages to brain. Glutamic acid plays a vital role in metabolism of fats and sugars, and assists in transporting potassium into spinal fluid and across the blood-brain barrier. Though it doesn’t cross the blood-brain barrier as readily as is done by glutamine, it is present in blood at high levels and may reach the brain in small amounts. The brain can utilize glutamic acid as a fuel. It assists in correcting personality disorders and is helpful in treating childhood behavioral disorders. It is also used in treating mental retardation, epilepsy, ulcers, muscular dystrophy, and hypoglycemic coma.

Glycine is an amino acid acting as a transmitter of the nerve impulses. It reduces the spinal nerves action by supplying skeletal muscles. Glycine tastes sweet and is hence added to soft drinks so that it masks the aftertaste of saccharin bitterness. This is an organic compound and is found in animal proteins. Glycine takes active participation in the free state in many significant reactions such as the biosynthesis of heme which is indeed one the important constituents of hemoglobin. The glycine defects in metabolism are rare. This acid is however not essential as diet as it can be available from other substances to the body. This was the foremost acid to get isolated from protein. Glycine is employed in pharmaceutical applications. Glycine is sold as United States Pharmacopeia as well as technical grade. However, the USP grade has diverse uses. The technical grade may sometime not reach the standards or USP grade, but is widely used in industrial applications for metal finishing.

Histidine is an amino acid that is essential especially in infants. The adult body produces this amino acid naturally and thus it becomes a non-essential acid. However in the case of infants this is not true. This vitamin is extremely important and children may not have sufficient Histidine. The Histidine is an originator of the Histamine which is a compound that is release by the human immune system when an allergic reaction takes place. This is also essential for the repair and growth of new tissues and helps to maintain myelin sheaths (the protectors of the nerve cells). Histidine is also needed for the production of the red and white blood cells.

Hydroxylysine

Hydroxyproline is a non-essential amino acid and it does not acquire directly through the diet. It means that it is produced from other amino acids present in the liver. It is necessary for the building of the human body's chief structural protein, known as collagen. Defects in the collagen synthesis can lead to internal bleeding, easy bruising, increased threat of blood vessel damage and the breakdown of connective tissues of the tendons and ligaments. Increased fall of hydroxyproline in urine is usually associated with the breakdown of connective tissues and may be a symptom of vitamin C deficiency. Deficiency of hydroxyproline happens only when a deficiency of vitamin C occurs.

Isoleucine- An important essential amino acid is isoleucine which is also part of the three “branched chain amino acids” along with leucine and valine. Since it is an essential amino acid it cannot be synthesized in the body and thus isoleucine has to be ingested in the diet (almonds, chicken, eggs, cashews, fish, lentils, liver, meat etc.). Isoleucine is required for muscle recovery and also for the formation of haemoglobin. Isoleucine also assists in regulating blood sugar levels and energy levels. It is also involved in blood-clot formation. Isoleucine deficiency is present only in those people who are lacking in protein intake. Deficiency may lead to dizziness, fatigue, depression etc. Excessive amounts of isoleucine doesn’t seem to be a problem though it isn’t recommended for those with kidney or liver disease.

Leucine is an essential amino acid that works together with isoleucine and valine, forming the three branched chain amino acids (BCAA). Leucine is easily converted by to body to glucose, helping to regulate and maintain the blood sugar level. Leucine promotes muscle recovery, muscle repair and provides the body with energy. It also helps in burning fat that are least responsive to exercise and dieting. Leucine helps in toning the body and the muscles. Leucine prevents muscle loss by breaking down and converting to glucose, this prevents the body from breaking down muscle tissues to create energy, particularly during intense workouts and heavy weight lifting.

Lysine is an essential amino acid that is sometimes also referred to as amino acid K. It is effective in preventing atherosclerosis which causes the walls of the arteries to harden caused by deposits of lipoproteins or fats. It is able to loosen and preventing the deposits of fats and reduces the risks of stroke and hypertension or high blood pressure. It also promotes the production of carnitine that converts fatty acids into energy. It also controls the blood pressure level. Lysine also helps in the absorption of calcium that keeps the bones healthy. It also promotes collagen production that is important in maintaining the joints and connective tissues healthy.

Methionine is an amino acid that is found in meat, fish, beans, eggs, lentils, onions and seeds. It contains sulphur that is essential for the production of glutathione. It helps the body get rid of toxins, build strong and healthy tissues, and promote a healthy cardiovascular system. It helps breakdown fats and promotes weight loss. It also prevents the build up of fats in the arteries that reduce the risk of arteriosclerosis. Methionine promotes proper digestion and gets rid of toxins and heavy metals in the body. It helps cleanse the body from toxins. It also helps relieve pains caused by arthritis. It helps in alleviating the mood, and treat depression.

Phenylalanine is an essential amino acid that plays an important role in the formation of proteins. It is converted into tyrosine in the body which stimulates the production of dopamine, epinephrine and norepinephrine. It helps treat and manage the symptoms of Attention Deficit Hyperactivity Disorder (ADHD), depression, and Parkinson’s disease. It also alleviates the symptoms from alcohol withdrawal. It also has the ability to reduce pains caused by osteoarthritis, rheumatoid arthritis and premenstrual syndrome (PMS). Phenylalanine also treats vitiligo, a skin pigmentation disorder. Phenylalanine may also help in weight loss because it aids in suppressing the appetite and cravings, and at the same time, it promotes the production of energy.

Proline is an amino acid. The body has the capability to produce Proline with glutamic acid. Proline works well with vitamin C, which make it more potent. It helps particularly in maintaining and repairing damaged tissues, skin and muscle. It heals damaged cartilage, and helps maintaining flexible joints. It benefits parts of the body where collagen is found, such as blood vessels, tendons, skin, bones, and including the eye. It prevents and reduces the sagging, wrinkling and aging of skin. It ensures that the body has the proper supply of collagen, guarding it against future joint and spine problems. It also enhances the immune system.

Serine is a non-essential proteinogenic amino acid that occurs naturally in the body. It is derived from the metabolite glycine. It is important to overall health, both physical and mental, as well as the proper functioning of the brain and central nervous system. It is an important factor to the biosynthesis of purines and pyrimidines, which directly affects the body’s metabolic rate. Serine forms the phospholipids that are needed to make cells in the body. Promotion of a healthy immune system is also one of serine’s benefits, as it produces immunoglobulins and antibodies. Serine produces trypophan which is an amino acid that is used to make serotonin.
